Due to the abundant amount of iron, many martensitic stainless steels are magnetic. Surgical stainless steel is a specific type of steel that is used in medical applications. Adding a touch of brass can add an element of sophistication and style to any room. Titanium is stronger and lighter in weight compared to stainless steel. It has to be stressed that the ferrite element should not be incorporated into stainless steel as this gives the metal a magnetic property, which is never used for surgical implants as it could interfere with Magnetic Resonance Imaging (MRI) equipment. It is important that a surgical implant is not susceptible to corrosion when placed inside the human body to prevent the chances of infection occurring. Surgical cutting instruments are often made from 440 or 420 stainless due to its high hardness coupled with acceptable corrosion resistance. Hence, they might have better magnetic properties than diamagnetic materials but cannot be regarded as magnetic as well. The zinc coating will not enhance the magnetic properties of the steel, but as long as the underlying metal is magnetic, the galvanized steel as a whole will have magnetic properties. So steel is magnetic, right? AISI 301is mostly used for manufacturing springs, which are useful in medical instruments. Stainless steels chromium content is largely responsible for increasing the alloys corrosion resistance it prevents the iron from oxidizing. Others believe that stainless steel must be magnetic because it contains iron. For example: 1018 steel, a very common grade of steel, is composed of 98.81-99.26% iron. Martensitic stainless steels (which have a ferritic microstructure) are magnetic. Electricity and Magnetism: What Are They & Why Are They Important. Stainless Steel May or May Not be Magnetic.
